I doubt it. Pummelling Iraq senseless will only drive the hardcore anti-American faction deeper underground and further harden their hearts.

The Czechs didn't kill Heydrich because he was an old softy and gave them too much leeway, after all. They did it right under the Nazi nose and, I'd guess, fully aware of the reprisal they'd face. Didn't stop them.

It's not possible to punish the resentment out of someone, or out of a society. Each time we kill an insurgent, we run the risk of turning an entire family against us. It's the mathematics of violence and hatred: how do you ensure that your enemy's numbers will never diminish?

Start killing them.
